"Find unlinked files" freezes when using for PDF

[soerenwolfers]

Using "Find unlinked files" does not work.
Scanning the directory works fine, but when I press "Apply" it displays "Importing into Database..." without ever making progress.

The problem occurs only for PDFs. It is independent of filename and directory. It is also independent of file content, i.e. it even occurs for empty PDFs.

I am using Windows 7 and the problem occurs for both JabRef 2.11.1 and JabRef 3.0

Thank you for opening the issue. We are open for pull requests fixing this bug.

I don't know what that means, but I assume I have to wait for the next release?

@Bananach We are working on it.

Confirmed. I can reproduce something when I click on apply and then close the window which is openend after clicking on apply - which makes JabRef unusable.

@Bananach You can try the latest build at http://builds.jabref.org/master/. This issue should be fixed there.

i have used the newest build http://builds.jabref.org/master/JabRef-3.8.2-dev--snapshot--2017-01-16--master--9e48a5ff8.jar and use debian stretch with Java (oracle tested:
ou have the recommended Java installed (Version 8 Update 111

the find unlinked works for the first file, sometimes even for the second (if the window is closed in between) fails later. it fails immediately if more than one file is selected from the unlinked files.
the feature would be a great help - please fix it!
thank you!

I can confirm that the bug is still there in the latest dev version. I will have a look.
